500A Battery Monitor/Coulometer with Bluetooth


500A Bluetooth Coulometer Battery Monitor with Shunt

The AMPTRON® battery monitor is a high-precision current-type battery capacity meter (also known as a coulometer) designed to monitor the performance of battery systems. The unit continuously measures voltage, charge and discharge current, energy consumed, and remaining battery capacity (State of Charge). This information leads to more efficient use of the battery system.

The product can monitor most battery types, including Lithium-ion, Lithium Iron Phosphate, Lead Acid, and Nickel-metal Hydride batteries with a working voltage from 8V to 80V.

The monitor can monitor large continuous current flows of up to 500A continuous.
